Here is your review
0:00 - 0:23 I like your mellow chord instrument. May just need a tad more reverb but nice job. As for the sub bass...well I think you need another less "subby" bass so I can hear it better especially when that new lead fades in.
0:23 - 0:52 The lead and accompanying instruments sound rushed. Lack of a better word: poor samples. The composition is unique but at the same time quite disorganized/messy. Were you using sidechaining on the kicks? Not a good idea when you have kicks going rapidly as in 0:35 - 0:52.
0:52 -end Better here with the bass but the other instruments again play some ackward composition. Originality is good, but originality while staying catchy is an art. There is no easy way to get better at this. Just need the inspiration.
I know things have changed from the old NG days when 4mb was the max limit for songs. This forced the producers of that time to work hard on their mastering. I can tell from the quality of instruments you used that you uploaded a very high quality version of your song. Practice to make your song sound good at poor quality. This will help you work out the mastering and even the mixing concerns. Best of luck in your future songs. Keep with the originality...just a little more organized and tighter instruments. 5/5
